For example, the vast majority of people with memory loss do not have problems with a loss of self-identify (meaning that they know exactly who they are).

Stroma is the thick fluid within the chloroplast. I think you mean 'Stroma'. Stroma can refer to two things in Biology. Stroma is the fluid inside chloroplasts, the site of photosynthesis in all plant cells. It is also, however, the framework (like a skeleton) inside any biological tissue, cell or organ.
A grana is the plural of granum. A granum is a stack of thylakoids found in chloroplasts--they look like stacks of pancakes (thylakoids). Grana is multiple stacks of thylakoi â¦ ds found in chloroplasts in the cell. The light reaction of photosynthesis takes place in the thylakoids stacked in grana.
